- Snakeblood I: Reduces duration of negative effects in potions by 50% when consumed.
- Snakeblood II: Reduces duration of negative effects in potions by 80% when consumed.
- Snakeblood III: Reduces duration of negative effects in potions by 100% when consumed.
Snakeblood reduces the duration of any negative effects in potions you consume. Note that while this is an Alchemy skill, it affects all potions, not just ones you create yourself. Likewise potions you create will only have decreased duration for you, not for other players you give them to (unless they also have points in this passive).
